Deck Primer

Long live the OTK, toolboxing is under the sea now. Deck wants to set up the backrow to kill in a turn with a stack coming from the breeding. If struggling with redirect effects, consider running BT19 Huankun, but it is a brick. The EX12 stuff unfortunately does not help the OTK, it wants to play control instead.
